Comment (by fbissey):
OK the current default in `sage` is to build ATLAS but Volker and I have
been in this conspiracy for at least a couple of year to make `sage` use
any blas/lapack we like - mirroring a possibility already existing in
sage-on-gentoo.
We left a track of tickets, although there has been a few private emails
as well, starting with bringing pkgconf in `sage` (although it had other
side purpose) then its python interface. So we got the current ATLAS spkg
install a .pc and probably also the optional openblas spkg and started to
make use of .pc files all over the place.
numpy/scipy was the latest place not using the .pc file for blas/lapack
and I made it behave, with a slightly lighter hand than what is done in
pure Gentoo actually.
There has been the occasional email on sage-devel about using MKL and
other alternatives blas/lapack but only few people have shown a big
interest.
